Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Embodiment one

This embodiment provides a method for service transmission, which is applicable to a network architecture including multiple services, especially an SDN architecture. The executor of this embodiment is an apparatus for service transmission. The device for service transmission is used to obtain the destination node to be reached by the service data flow according to the service feature identifier of the service data flow sent by the service node, and send the service data flow to the destination node. For example, the service transmission device may specifically be a server or a computer, and similarly, the service node may also be a server or a computer. The services in this embodiment may be caching services, firewall services, application acceleration services, encryption services, decryption services, etc., which are not limited here. Each service node can correspond to one or more services, which can be set according to actual needs.

As shown in FIG. 1 , it is a schematic flowchart of a method for service transmission according to this embodiment.

Step 101, when receiving a service data flow sent by a service node, obtain a destination service identifier of the service data flow according to a service feature identifier in the service data flow.

When a service node initiates a service or finishes processing a service, it sends the service data flow of the service to the service transmission device. When the service transmission device receives the service data flow, it searches for the target service identifier according to the service characteristic identifier carried by the service data flow itself. The service feature identifier may include at least one of the following: the source service identifier of the service data flow, the user identifier, and the identifier of the service data flow, wherein the user identifier is the identifier of the initial sender of the service data flow, that is, the client that generates the service data flow logo. Specifically, it can be set according to actual needs. It is sufficient as long as the destination service identifier of the service data flow can be obtained according to the service characteristic identifier. The source service identifier of the service data flow here refers to the identifier corresponding to the operation performed by the service node on the service data flow. It is conceivable that the source service identifier is the service that the data flow of the service node reaches the service node logo.

Step 102, obtain the destination node identifier of the service data flow according to the destination service identifier.

The device for service transmission acquires the destination node identifier corresponding to the service data flow according to the destination service identifier, that is, the destination node identifier capable of processing the service data flow. The destination node identifier can be the MAC (Media Access Control, Media Access Control) address, IP address, MPLS (multi-protocol label switching, multi-protocol label switching) label or VLAN (Virtual Local Area Network, virtual local area network) value of the service node.

Step 103, sending the service data flow to the destination node corresponding to the destination node identifier.

According to the service transmission method of this embodiment, the service transmission device receives the service node to process the service data flow, and determines the destination service according to the service characteristic identifier in the service data flow, and then determines the corresponding destination node according to the destination service, and then the The service data flow is sent to the destination node. In this way, each service node does not need to care about where the service data stream needs to be sent, and the query and forwarding operations are completed by the service transmission device, which reduces the burden of each service node and improves the efficiency of each service node's service processing. Moreover, acquiring the destination node identifier of the service data flow through the destination service identifier of the service data flow facilitates service expansion.

Embodiment two

This embodiment provides a service transmission method based on the first embodiment.

As shown in FIG. 2A , it is a schematic flowchart of a service transmission method according to this embodiment.

Step 201, when receiving the service data flow sent by the service node, according to the service characteristic identifier in the service data flow, obtain the destination service identifier of the service data flow in the preset service identifier list.

The service characteristic identifier includes at least one of the following identifiers: a source service identifier, a user identifier, and an identifier of the service data flow. The source service identifier is the identifier that the service node encapsulates into the service data flow before sending the service data flow to the service transmission device. The source service identifier may be the identifier of the service generated after the service node processes the received service data flow. For example, when the service feature identifier includes the source service identifier and the user identifier, the device for service transmission may first obtain the destination service identifier corresponding to the source service identifier from the preset service identifier list according to the source service identifier. When the transmission device obtains multiple destination service identifiers, it further determines the destination service identifier according to the user identifier, and so on until the service transmission device determines a unique destination service identifier.

Step 202, according to the destination service identifier, obtain the destination node identifier of the service data flow in the preset service node list.

The device for service transmission searches for the corresponding destination node identifier in the service node list according to the acquired destination service identifier. When multiple destination node identifiers are found, the service transmission device can randomly select one of them as the destination node identifier of the service data flow, or select one of them as the destination node identifier of the service data flow according to the Load Balance principle. The principle of load balancing belongs to the existing technology, which is used to balance the load among various business nodes. The business data flow is first sent to the business node with light load for processing, which is conducive to improving the efficiency of business data flow processing, and the details will not be repeated. . It is also possible that the service transmission device uses the multiple destination node identifiers as the destination node identifiers of the service data flow, that is, the service transmission device sends the service data flow to all the queried multiple destination service identifiers.

In step 203, the destination node corresponding to the destination node identifier searches for a transmission path in a preset path table, and sends the service data flow to the destination node according to the transmission path.

The routing table includes the transmission paths between service nodes, and the routing table can specifically be a routing table, a MAC (Media Access Control) table, or a label forwarding table. Specifically, if the service transmission device can directly send the service data flow to the destination node, it will send it directly. If the service data flow needs to be transferred through other service nodes, the transmission path can be encapsulated in the service data flow by each service For forwarding by the node, the transmission path may also be issued to each service node on the transmission path, so that each service node forwards the service data flow according to the transmission path after receiving the service data stream, and details will not be repeated here.

It should be pointed out that the above-mentioned service identifier list, service node list and transmission path list can all be stored in the query list, or can be stored separately in other stores.

Optionally, the device for service transmission updates the service identification list, the service node list and the routing table every preset time. It is conceivable that when the service node changes, the contents of the above tables can also be updated immediately.

Optionally, when the destination node identifier of the service data flow is not obtained according to the destination service identifier, the service data flow is sent to the router or the network. When the service transmission device cannot obtain the destination node identifier, it means that the service data flow has been processed, and the service data flow needs to be sent to the router or the network.

According to the service transmission method of this embodiment, by setting three-level lists, namely the service identification list, service node list and route table, it is beneficial to the update of the service, that is, when the service changes, the corresponding service is updated according to the specific content of the service change. table, easy to operate. For example, when the service identifier changes, only the service identifier list and the service node list need to be updated, and when the service node list changes, only the service node list and the routing table need to be updated, which is conducive to business expansion and contraction.

Embodiment three

This embodiment provides a specific service transmission method based on the foregoing embodiments.

As shown in FIG. 2B , it is a schematic structural diagram of the method for service transmission according to this embodiment.

First, service data streams in the network may first enter the router 210 . A flow table is preset in the router 210, and the flow table is used for encapsulating a destination service identifier and a destination node identifier for a service data flow. The router 210 finds the forwarding header data information of the data flow according to the flow table, and encapsulates the forwarding header data information in the service data flow, including service feature identifiers specifically sid=1, userid=1, and flowid=1. Wherein, sid is the source service identifier, userid is the user identifier, and flowid is the identifier of the service data flow, and the first service node 211 to send the service data flow to. The IP address of the service node 211 is found to be 192.168.1.100 through the query of the flow table.

After receiving the service data flow, the service node 211 processes it, changes the sid to the processed target service identifier, ie sid=2, and sends the processed service data flow to the service transmission device 220 . The service transmission device 220 searches the service identification list preset in the service transmission device 220 according to the service feature identifier of the service data flow, that is, sid=2, userid=11, flowid=1, and finds the corresponding service data flow The destination service ID is 3, and according to the destination service ID 3, it is found in the preset service node list that the IP of the next service node to which the service data flow will be sent is 192.168.1.101.

Next, the service transmission device 220 sends the service data stream to the second service node 212 according to the preset route table, and the service node 212 is the destination node found by the service transmission device 220 according to the destination service identifier 3 . After receiving the service data flow, the service node 212 processes it, and changes the sid to the processed target service identifier, that is, sid=3. In this way, the service characteristic identifier of the service data flow becomes: sid=3, userid=192.168.1.101, flowid=1.

Next, the service node 212 sends the processed service data flow to the service transmission device 220, and the service transmission device 220 cannot find the corresponding service data flow in the preset destination service class table according to the service characteristic identifier in the service data flow. If the destination service identifier is specified, the forwarding header information in the service data flow can be removed, and according to the default setting, the service data flow can be directly sent to the network or sent to the router 210 by encapsulating a preset special forwarding header.
